The VC-EP6604-MINI provide 4 GE interface for uplink, and 4 EPON ports for downstream. It can support 256 ONU under 1:64 splitter ratio. Each uplink port is connected to a EPON port directly, each PON port behaves as an independent, that EPON OLT port and there is no traffic switching between PON Ports and each PON port forwards packets to and receive packets from one dedicated uplink port.

VC-EP6604-MINI provides the full management functions for onu according to CTC standard, Each of the 4 EPON OLT ports is fully compliant with IEEE 802.3ah standard and CTC 2.1specification for SerDes, PCS, FEC, MAC, MPCP State Machines, and OAM extension implementation. Both upstream and downstream are operational at 1.25 Gbps data rates.
